SPECIFICATION forming part of Letters Patent No. 790,686, dated May 23,1905. Application filed December Z4, 1904. Serial No. 238,198.

T all whQm-,L't may con/cern,.-

Beit known that I, ANDREW J. JOHNSON, a citizen of the United States,residing at Curia, in the county of Independence and State of Arkansas,have invented a new and useful Plow, of which the following is aspecification.

This invention relates to plows of the class wherein a rotative cuttingmember is employed to produce the pulverization of the soil, and has forits object to improve the construction of such devices and increase theeciency and at the same time reduce the expense of manufacture. f

With these and other objects in View, which will appear as the nature oftheinvention is better understood, the same consists in certain novelfeatures of construction, as herein after fully described and claimed.

In the accompanying drawings, forming a part of this specification, andin which correspondi'ng parts are denoted bylike designating characters,is illustrated the preferred form of embodiment of the invention capableof carrying the same into practical operation,

it being understood that the invention is -not necessarlly limitedthereto, as various changes in the shape, proportions, and generalassemblage of the parts may be resorted to without departing from theprinciple of the invention or sacrificing any of its advantages.

In the drawings, Figure l is a longitudinal sectional elevation'.l Fig.2 is a kplan view, partially in section, of the improved device. Fig. 3is a sectional detail of the releasing mechanism. Fig. 4 is a sectionaldetail, enlarged, of the combined tool-box and adjustable seat-standardsupport.

The improved implement comprises an axle 10, having bearing-wheels 11 12mounted for rotation thereon and provided with ratchethubs 13 14 forengagement by spring-comtrolled pawls fast. to the axle and partaking ofits motion, so that when the wheels move forward the axle will berotated with them, but will not be moved when the wheels run backwardly,as will be obvious.

The ratchet-hubs and pawls are alike at both Sides of the device; butfor the purpose of illustration one only of the same is illustrated 'at15 in Fig. 2.

Mounted to swing-upon the axle 10 is Ia frame 16, carrying thedraft-tongue 17, the latter extending forwardly of the axle and at oneside of its center, so that the draft-animals will travel upon theunplowed land, as hereinafter explained.

Mounted to swing upon the axle 10 and extending rearwardly ofthe same isa frame formed of spaced side members 18 19 and 60 transverse members 20and having a shaft 2l mounted for rotation upon the side members. Theshaft 21 is provided with spaced hubs 22 23, having radiating arms 24 25connected at their outer ends by cutting-blades 26, the latterdisposed-parallel to the shaft and its hubs. The hubs, arms, andcutting-blades thus form an open drum having spaced peripheralcutting-blades, as shown.

Mounted to move longitudinally upon the 7C axle 10 is a-gear 27, causedVto partake of its rotary motion, as by a feather-key 28 on the axlefitting a corresponding channel in the hub 29 of the wheel in the usualmanner. The wheel 27 is adapted to be moved longitu- 75 dinally of theaxle by a shipperlever 30, mounted for longitudinal movement upon thetongue-frame 16 through a keeper 3l, attached to the tongue-frame, thelever having spaced notches 32 33 for engaging the 80 keeper to supportthe lever in either one of its two positions, and the inner end of therod 30 will be upturned, as at 39, and located convenient to the `footof the operator. The gear 27 engages a pinion 34 on a stub- 85 shaft 35,attached rigidly to the frame member 18, the pinion having a larger gear36 integral therewith and engaging a pinion 37 on the shaft 21. 'By thisarrangement it will be obvious that when the shipper-lever 30 is in 90one position the gear 27 will be in mesh with the pinion 34 and rapidlyrotate the shaft 21 and its cutting-drum as the machine is drawnforward, and when the shipper-leveris moved into its other position thegear 27 will be disl95 connected from the pinion 34:, thus cutting offconnection between the drum and the axle. Connected, as by bolts 48, tothe frame 16 above the draft-tongue 17 is a tool-box 49, having inclinedsockets 51 to alternately receive the standard 52 of the drivers seat38, the standard being held in place, as by set-screws 53 54. By thismeans the seat may be adjusted to provide means whereby the weight ofthe driver may be utilized to increase or decrease the tension upon thecutting-drum, as will be obvious.

Pivotally attached to the frame 16, as at 40, is a lever 4l, having apawl 42 for engagement with a notched segment 43, and the cutting-drumis provided withahousing or cover 44, attached to the transverse members2O of the cutting-drum frame and firmly supported by a relatively heavyarched frame member 45, having a central lug 46, between which and thelever 4l a connecting-rod 47 extends. By this arrangement it will beobvious that the cutting-drum frame is adjustably supported relative tothe draft-tongue and its frame and may be adjusted to cut any desireddepth or elevated entirely free from the ground, as may be required.

As before stated, the draft-tongue is located at one side of the center,so that the horses will travel upon the unplowed land, and as they moveforward the cutting-drum is rapidly revolved, thoroughly pulverizing theearth and leaving it in proper condition for planting without furtherattention.

With a plow thus constructed harrowing or further reducing will notJ berequired, as the soil is so thoroughly pulverized as not to require theuse of such implements. The laborof preparing the soil for the crops isthus very materially reduced, and the soil placed in a much bettercondition than by the use of the ordinary plow.

The machine may be constructed of any size or capacity and of anysuitable material, and any number of the blades 26 may be employed uponthe cutting-drum- Having thus described the invention, what is claimedis- In an implement of the class described, an axle having transportingwheels, a frame mounted to swing upon the axle extending forwardly ofthe same and having a drafttongue, a frame mounted to swing upon theaxle and extending rearwardly of the same, a member mounted for rotationupon the rearward-extending frame, earth-engaging cutting-bladesconnected with said rotary member, means for transmitting motion fromone of the transporting-wheels to the rotary meniber, a housing for saidrotary member mounted upon the swinging rear frame, a reinforcing memberfor said housing having an upwardly-extending arm said reinforcingmember being securely connected with the housing and with thesupporting-frame, a hand-lever fulcrumed upon the front frame, a linkconnecting said lever with the arm extending from the reinforcement ofthe housing, and means for retaining the lever at various adjustmcnts.

In testimony that I claim the foregoing as my own I have hereto aiiixedmy signature in the presence of two witnesses.

ANDREW J. JOHNSON.
